It includes information on synagogues, Jewish cemeteries and Holocaust sites in about three dozen towns. Much of the data dates from the early to mid-2000s.

Most of the sites are abandoned or ruined -- and some were the scene of heavy fighting during the Bosnian war in the early 1990s. As late as 2005, the report notes, mines were believed to still prove a danger in the ruined Jewish cemetery in Derwenta.

Much of the onsite research was carried out by Ivan Ceresnjes, a former leader of the Bosnian Jewish community who is now with the Center for Jewish Art in Jerusalem.
